While he's not obsessing over cutting the length of school holidays or scrapping A Levels and GCSE's, it seems Tory Education Secretary Michael Gove has another fixation.

According to his wife, Sarah Vine, Gove was once preoccupied with the size of Mick Jagger's penis. Speaking to The Telegraph, she told how Gove and Jagger once stood together at a urinal at the University of Oxford shortly after Gove had graduated. The secretary of state had been invited to address the university's union on the same night as the frontman. "For some bizarre reason, this encounter inspired [Michael] to pepper his arguments with a series of double-entendre jokes about the underwhelming size of Jagger’s equipment," she said.

Naturally, this didn't impress the rock legend much. Vine went on to recall that at the post-debate dinner, Gove asked Jagger if he was going back to London that night and asked him if he could have a lift. "Sure, why not?” Jagger said, according to Vine. "In the fucking boot."

This isn't the first time Jagger's manhood has been under such scrutiny. Last year, The Who's Pete Townshend told a press conference: "What I remember of the size of Mick Jagger's penis - I remember it as being huge and extremely tasty." The comment followed Keith Richards' less complimentary words about his bandmate's member, which he notoriously made in his autobiography, Life.
